DAVID STONER, OF WHITE PIGEON, MICHIGAN PUMP.

SPECIFICATION forming part of Letters Patent No. 370,428, datedSeptember 27, 1887.

Application filed November 26, 1886. Serial No. 220,534.

To all whom it may concern:

Be it known that 1, DAVID STONER, a citizen of the United States,residing at WVhite Pigeon, St. Joseph county, State of Michigan, haveinvented a new and useful Improved Balance-Wheel for Pumps, of which thefollowing is a specification.

This invention relates to an improvement in balance-wheels which areespecially applicable to lifting and suction pumps, which improvementwill be fully understood from the following description, taken inconnection with the annexed drawings, in which- Figure 1 is a frontelevation of a liftingpump, partly in section, having my improvedbalance-wheel applied to it. Fig. 2is a vertical section of the balancewheel and upper part of the pump.

Referring to the said drawings by letter, A designates the upper part ofa pump stock, and B the plunger rod, which is hung from the crank G of ahorizontal shaft, 0, suitably journaled in the pump-stock A. On one endof the shaft 0 is keyed a balancewheel, D. This balance-wheel isprovided with a crankhandle, 0, which is suitably secured to the box F,preferably of circular form. Concentrically (No model.)

to this box, opposite to the handle 0, a pin is suitably secured, whichpasses through the rim of balance-wheel and is fixed to its rim.

I am able to regulate the balancing-weight according to the length ofthe plunger-rod and force to be overcome.' This is done by introducingdifferent weights adapted to be secured to the wheel. Furthermore, itwill be observed that the wheel can be very accurately adjusted tobalance theload tobe raised by varying the Weight put inthe box E.

I am aware that it is very common to apply weights to balance-wheels andto provide such wheels with adjustable weights, and therefore disclaimthis feature, broadly considered.

What I claim is The combination, with a balance-wheel on a crank-shaft,of a weight-receiving box, F, provided with a crank-handle, c, on oneside, and on the opposite side a device for fastening the box and handleto the said wheel, substantially as specified.

DAVID STONER.
